As separate debug threads need to be started for each core to be debugged, and the method for launching a debug thread differs depending upon whether it is a primary core or secondary core and if the executable image will be loaded or if the executable is alre...
Since I want to implement energy equation to original interFoam solver, I started from test the interFoam by debug tool--gdb. For example, in order to read the value of rho1 and rho2, I break interFoam in gdb like: b alphaEqn.H:26 and it do stops at that point. However if ...
When it comes to performance, NGINX can easily handle a huge amount of traffic. The other main advantage of the NGINX is that allows you to do the same thing in different ways. Unlike traditional HTTP servers, NGINX doesn't rely on threads to handle requests and it was written with a ...
Sidenote: “in most cases”: sometimes you have to swap threads (or use: ‘thread apply all bt’ or ‘thread <nr>’ then ‘bt’) before you can view the actual crashing statement: gdb may have incorrectly analyzed which thread caused the crash. Inspecting the error log (which also ...
If you want to get afullbacktraceofallthreads, then you could execute the following: thread apply all bt -frame-arguments all full If you want to get a full backtrace to a file to report a bug, the recommended way is to use gdb: ...
Tto create a stack trace for all the threads in PASOE it is possible to use the GDB debugger like this: gdb --pid=<PID# of multi-threaded process>-ex "thread apply all bt" -ex "detach" -ex "quit" > PID_stack.txt NOTE:If gdb does not detach from the process and ...
If the given application's uid is in the background and waiting to become idle (not allowing background services), do that now. Spoiler: MONITOR monitor [--gdb <port>] Start monitoring for crashes or ANRs. Spoiler: OPTIONS --gdb
